Bio-chemical indexes indicated as well that aerobic exercise effectively alleviated retrained stress induced changes of behaviors and monoamine neurotransmitters. Conclusion: restrained stress will cause changes of social communica-tion and emotion related behaviors, while exercise intervention will play an effective role of alleviation. |
